I know this is an old thread, but the link provided didn't do it, here's some info I found online:
Buerger-Allen Exercises
- Life flat - legs up for 2 min. or until blanching
- Place legs in dependent position, until cyanotic/red
- Lie on horizontal position for 1 min.
- Repeat exercise 4x - 3x daily
From here (it's in the middle of a PPT):

Oops, didn't see Chris' quote, that's very good. Will ask my PT cousin if he has more.
